Will do. The iperf3 step already produces GSO skbs, but veth hands them
to the peer as CHECKSUM_PARTIAL and the receiver treats them as already
verified, so a bad seed is never caught. The next revision will add a
variant with tx checksum offload disabled on the egress veth, so
software GSO computes the final checksums and the receiver actually
verifies them.
Thanks!
